Surveillance video captured the vicious beating of a 62-year-old woman who was robbed in the lobby of a Bronx apartment building, police said.

The suspect (pictured here) grabbed the woman from behind in the Bedford Park building around 3:40 a.m., June 29, cops added. He threw her to the floor and fought with her before grabbing cash and running away from the Briggs Avenue crime scene, police said.

The woman was treated at an area hospital for minor injuries and released, authorities said.

The suspect is 5-foot-9, about 200 pounds with short black hair, cops said. He was last seen wearing a white t-shirt, dark shorts and white sneakers.
